chine disclosed in the, patent to Had'awayx 29', 1898. This ma verticalslide 13 in Fig. 3 andfbroken away, in Fig. 1. The

usual insidejformer which is supported upon one arm of a bell crankindicated at 17 is caused to yieldingly engage with the inner side ofthe lip through the provision of the spring 18, thestem of the formerbeing shown broken away at 19, Fig. 1.- T he forming members cooperatein the usual'fmanmg fabric about thelip of the insole, all

as fully described in the Ha daway patent her'einbe'forepreferred to. yI

It is highly desirable in this type of machine that the reinforcingfabric shall be severed cleanly along'a line conformingto ner to feedthe Work and shape the r'ein'for'cthe general contour o-f the insole andin such a manner shall not'show after the insole is incorporated in aboot or shoe. fTo this'e'nd the fabric is severed, after it has beenlaid upon the feather by the forming tools; along'a line which is spaceda' uniform" distance from the base of the lip and slightlylwithin the"edge of the insole. 'The trimmingof that the edge ofthej' fabric thefabric s' 'accomplished by a stationary drag'knife which engages andcuts the fab Lric during the feeding of the insole, a vpresser footwhich rests upon. the feather of the insole controlling the-depth"ofrut. For thispurpose, a drag knife'20.is fpi' o- ,vided, beingreceived in a knife block 21 pivoted upon'a fixed bracket 22. The knifeblock 21 is provided Withan r mped lower end 25 having one portionextending substantially in the line of feed at'the side of y the knifeand a second portion at right angles thereto extending across the lineof feed which rests upon the face of the insole and acts as a presserfoot to gage the depth of cut made by the knife. This lower portion ofthe knife block is curved deflecting, surface 26; which serves to directthe severed portion of the fabric out of the machine. pivoted upon afixed stud 28 clamped at one end in a split hub 29 formed upon thebracket 22, a clamping screw 30 serving to draw the two parts of the hubtogether and bind the stud in position. The hub portion of the knifeblock 21 is provided with an upwardly extending taii 31 which carries anadjusting screw 32 adapted to limit the downward movement of the freeend of the knife block through contact. with the opposing face-of thebracket 22", as shown clearly in Figs. 1 and 4. The knife block andknife carried thereby are normally pressed into engagement with the workby a plunger 35 slidingly received within the bracket 22' and engagingwith the upper face of the knife block a spring 36 serving to apply therequisite pres- Sure to the plunger. It will be noted that this bracket22" conveniently carries the stationary outside former 15 which isadjustiably fastened thereto through a screw and slot connection,indicatedat 37. The stationary bracket 22 is connected to a. dependingportion 38 of the machine frame through tongue and groove connections 40and a clamping screw 41, as shown in Figs. 2' and 3, thus affordingprovision for a transverse adjustment of the knife and stationary formeracross the line of feed. In order to adjust the depth of cut made by theknife for varying thicknesses of reinforcing fabric or other reasons,the knife is provided with rack teeth 42 on the under edge which areengaged by a single toothed adjusting pinion 43, the side of which has aslot, as shown in Fig. l i,.into which a screw driver or other tool maybe inserted for rotating the pinion. The knife is clamped in adjustedposition in the knife. block by the head of a clamping screw 44. Withthis construction it will be noted that the trinnning knife cuts-to ameasured depth predetermined by the relation of the knife andpresses-foot both of which are yieldinglypressed against the work withsufficient pressure to properly maintain the presser foot in contactwith the'surface' of the feather. In order't'o' prevent injury to theknife if the machine is operated without an insole located. upon thetable, the latter is provided with a peripheral groove 4L6 positionedbeneath the knife and into which the knife. may enter when the tablerises under the influence of its spring; The screw 32 is so adjusted asto permit the knife to be yieldingly held against the sole whiletrimming the reinforce and,

therefore, the presser foot may extend. to a position slightly below thelower end of the stationary former l5.

It will be recognized by those skilled in the art that the canvastrimming feature of the machine herein describedis not limited in itsuse to a combination with head forming instrumentalities, but willperform for operating on, previously reinforced soles.

While it is preferred to employ the specific' construction andarrangen'ie'nt of parts shown and described, it will be" understood thatthis construction and arrangement is not essential except so far asspecified in the claims, and may be changed or modified withoutdeparting from the broader features of the invention.

The invention having been described, what is claimed is;

1. A machine for operating on reinforced insoles having, in combination,means for supporting and feeding the insole, a. knife having a cuttingbladeopposite the feather for severing the rei nforclng material alonga. line on the feather, a presser foot'independent of the feeding meansand" bearing on the feather to predetermine the depth of the out, andmeans through the actuation of which the relation of said knife and footmay be adjusted forvarying the depth oft-he out.

2. A. machine for operating on reinforced insoles having, incombination, a frame, means in the frame for supporting and feed ing theinsole, a knife having a cutting blade opposite the feather reinforcingmaterial along a line on the feather, a knife block adj'ustably securedto the frame and in which said knife is carried, a presser foot mountedon said block independently of the feeding means, and means through theactuation of which the relation of said l'mife and p'resser foot may beadjnste'd, and means by which said parts may be clamped in adjustedrelation.

3. A machine for operating on reinforced in combination, means forsupporting and feeding the insole, a knife having a cutting bladeopposite the feather for severing the reinforcing material along a lineon thefeather, and a knife block and presser foot to'wl'iic'h the knifeis adjustably clamped and constructed and arranged to predetermine thedepth of cut, the lower surface of said presser foot bearing on. thefeather over a substantial area both beside andbehind said knife in thedirection of feed;-

l. A machine for insoles having, supporting and operating on reinforcedin combination, means for feeding the ln'sole, a support for severingthe having a fiat Work-engaging surface, a knife opposed to saidsupport, for severing the reinforcing material along a line on thefeather, having its cutting blade normal to the surface of said support,a presser foot also having a flat, Work-engaging surface parallel to thesurface of said sup-portand bearing on the feather to predetermine thedepth of cut, means whereby the projection of said blade below said footmay be adjusted so that no substantial incision Will be made in thefeather and means acting continually to force the work support towardthe knife, said flat surface of the support being provided with a grooveto receive said blade when no Work is in the machine.

A machine for operating on reinforced insoles having, in combination, awork support, a drag knife opposed to said support for severing thereinforcing material along a line on the feather, means for feeding thesole past said knife, means for main- 6. In a sole trimming machine, aknife block, a knife carried thereby having a toothed shank, and asingle-toothed pinion rotatably mounted in the block with its toothmeshing with the teeth on the shank of said knife, whereby a rotation ofthe pinion will adjust the knife on the block.

7. In a reinforced-insole trimming machine, a fabric trimming knife, aknife block therefor, and a presser foot on said block to predete'rminethe depth of cut, said foot having a curved deflect-ing surface on itssole engaging end to direct the trimmed margin out of the machine. 7
